Place 3-4 pine cones on a flat outdoor surface away from direct rain but exposed to air. Mark their initial position with natural items like pebbles and check their status every 4 hours. Record the scale positions alongside actual weather conditions in a nature journal to track prediction accuracy. This simple tool demonstrates how biological materials react to atmospheric changes.
Building a Natural Wind Vane
Transform lightweight natural materials into a functional wind direction indicator. Start with a straight stick about 12 inches long as your base. Attach a large leaf or feather to one end using plant fiber or grass stems. Push the stick into soft ground or secure it to a raised platform. Place 4 marker stones in a cross pattern around the base representing North South East West directions. This design lets you observe wind patterns while teaching directional awareness. For enhanced accuracy add smaller leaves as counterweights to balance the main pointer.
Investigating Soil Properties and Composition
Testing Soil pH With Natural Indicators
Create your own natural pH indicators using red cabbage juice and common backyard materials. Collect soil samples from different areas of your yard then mix each with distilled water. Add your cabbage indicator solution to see color changes – purple indicates neutral soil while pink shows acidic conditions and blue-green reveals alkaline soil. Compare results between sunny vs shady spots and different garden zones to understand how pH affects plant growth. Try testing with other natural indicators like tea bags or flower petals for varied results.
Examining Soil Layers and Components
Set up a soil investigation station using clear glass jars to observe distinct layers. Fill each jar 1/3 full with soil samples then add water until nearly full. Shake vigorously and let settle for 24 hours. Watch as materials separate into layers based on particle size – sand sinks first followed by silt then clay on top. Use a magnifying glass to identify organic matter like decomposing leaves pine needles and small twigs floating at the surface. Measure and record layer thickness to compare soil composition from different locations.
